Good product/unsure of air seal
We love this to hold our coffee beans, but we aren’t sure if it truly seals air out. It seems to work great though and our beans taste fresh!

Does not hold a vacuum
It does not hold a vacuum. I am able to pump and cause a vacuum where I cannot take the top off without pushing the relief button but give it a few hours and the vacuum is gone. Coffee is stale in a few days and I have gained nothing but the expense.

Does not hold a seal very long
Looks good. Quality materials and construction. Vacuum seal doesn’t seem to last very long. After a day the lid can be easily opened, regardless of how many times you pump it beforehand. More aesthetic than functional.
